Bon Voyage is a 2003 French film directed by Jean-Paul Rappeneau, starring Isabelle Adjani, Gérard Depardieu, Virginie Ledoyen and Grégori Derangère; it's very loosely inspired by Professor Lew Kowarski's smuggling of the world's only supplies of heavy water out of France following its occupation by the Nazis.
